She apparently speaks a baby babble of both (because at such a young age it is impossible for her to recognize two distinct concepts of language). I think her parents said such in an interview a while back.

She is going to a special daycare center in Wassenaar twice a week. I believe only 5 other children are there at the same time, as they want to give the children as much attenton as possible & want to make it seem as if they were still at home. They have beds as well, where the toddlers can take a nap.
